rIhis invention relatesto metallic window, constructions, and more particularly to the' construction of easement windows of the. type adapted to 4provide access from wlthm to both sides of the window in its open position,

as for cleaning purposes. Y

It is a general object of the invention to simplifyand improve the construction and operation of devices of this character. y Y

Another object of the invention is toprovide a construction of this character in which there are no projections outside of the connes of the window frame. Y Y

Still another object of the invention is to provide a. means forautomatically providing access to the outer side of thefwindow'as it is swung open. x n Y,

A still further objectofthe lnvention 1s to provide an improved locking meansV for win- 1.2.x', dow construction Vwhich will also serve'as a means for holding the window open.

Other objects `and. features of novelty will be apparent as the following description proceeds, as taken in connection with the accompanying drawings, in which: a

Figure Gis an enlarged view ofthe lower corner of the .window construction such as shown in Fig. 4, but showing the sash in the open position; and

Figure 7 is an enlarged detail View similar to Fig. 3, but showing `the sash in the open position. Y v v Referring more .particularly` to the drawings, the window construction embodies essentially a frame 10 and a sash 11.- The frame 10 may be of any desired construction, butin the preferred form of the invention shown in the drawings it is constructed ofa rolled shape such as shown in Fig. 3, and comprising an angle having an inner flange12 and a leg 13 which is provided with an inwardlydirected flangel14 and two heel flanges 15 and 16; The lsash 11 comprises a rectangular frame constructed of a rolled shape somewhat similarf to the 4frame shape, but inverted with respect thereto. The sash angleY has a flange 18 adapted to overlie the flange 14, and a leg 19 having a heel flange 20 and an inwardly directed ange 21 which is adapted to overlie the outer portion of the frame flange 12. The k65 sash may be glazed with a single pane, but in the form shown in the drawings, muntins 22 and rails23 are provided for mounting a plurality of panes. 'y

The frame 10 comprises side bars 25 and 26, 70 an upper bar 27 and a lower bar 28. Correspondingly the sash 11v comprises stiles-y 30 and 31, and rails 32and 33.

The sash is pivoted to the frame in such a manner that the vpivot points may move ,7 toward thev center of the opening as the sash is swung outwardly, and at the same time the sash may move radially with respect to theV pivot so that the sash maytakea position outside of the confines of the window frame. Si,

`For this purpose-slides 34 and 35 are respectively secured tothe outer sides of thev sash Arails 32 and 33.A These slidevmembe'rs are each provided with a pair ofelongated open- 'ings37 and 38, respectively receiving headed .g5

Vpins 40. and 41 secured to therails between the flange 18 and the heel flange 21. This VVconstruction permits limited sliding `movement of the sash and slides, the slide moving inthe-plane of the sash, and the sash moving radially with respect to itspivot. The pivot comprises p'ins43 and 44respectively adapted to t an aperture in the end of the respective slides 34 and 35. y

To permit the pins :to move toward the 95 center of the opening when the slide is swung outwardly, track members 45 and V46 are Yrigidly secured to the upper'and lowerframe members 27Land 28. These tracks lie snugly against the base 13, between-the flanges l12 and 100' i 14 and comprise strips of sheet material of substantially channel shape, forming reentrant flanges and 51 respectively, which serve to retain a friction member 52, but permit the pin itself to pass therebetween.

To automatically cause the sash to move radially with respect to the pivot, spring means is providedto bear against the-pin, and in the present form a flat leaf spring is provided having its` upper end secured tothe stile 30 of the sash as by rivets 56' and 57' and having its lower free end 58 bearing against the upper end of the pin 43 which Vprojects through the slide member 34.

Retaining means is provided to limit the swing of the sashA about its pivots, such as the link 59, best shown in Fig. T. One end ofthe link is pivotedon av stationary pin 53 carrier by the lowerframe member 28, andthe other end of the link is pivotally received by the pin 41, as shown in 6 and i'.

When the windowpis in the Vclosed position the parts take the position shown in F 2 with the hinges 43VA and 44 andi their friction members 52 lying close against the inner frame member 25, and the spring 55 compressedV between the pin 43' and the sash niember 30. `When the window is opened, the spring 58 bearing against the-pin 43 will urge the sash radially of the pivot, causing therpins 40 and 41 to occupy the far-end of the slots 37 andv` 38. As shown iii Fig. 7 this :permits the flange 18 to ride outsideof the confines of the window frame and prevents marring of the finish and faulty operation. rlhen the stile 30 maybe grasped and pulled bodily toward the-center of the opening. This will cause the sash to pivot aboutthe pin 41, supported by the link 59.V Sufficient force must be exerted to overcome the resistance of the friction member 52 to cause it to ride in the tracks 45 and 46 and permit the pin to take the position shown in F igs. 6 and 7. e Y

lVith this arrangement an attendant may stand inside. the building and reach outward between the frame member 25 and the sash member 30 to-clean theoutside of the window. The inside of the window may be cleaned while it is in the closed position, or may of course be cleanedV while. the parts are inthe position shown in Figs.. 6 and 7, access being provided between the frame member 26 and the sash member 30.

'Fo-lock the window in the closed position, or toI hold the window partly open forrthe purposes of ventilation, there has beeny provided a device such as shown in Fig;V 5. This device comprisesa flat platel 60l fastenedto the flange 20 of the sash 19 and provided with aV pivot pin 61. Pivot-edI on the pin 61 is a clamping device havinglever arm 62 constituting av handle and ailocking arm 63 having acanr surface 64 adapted to swing" under a pad 'icarried by the fiange 12 of the frame. When the parts are in the position shown in full lines in Fig. 5 this device serves to securely lock the parts together in the position shown with the flange 21 fitting against the frame fiange 12 and the sash flange 18 overlying the frame fiange 14.

`When the window is opened and the handle 62 rotated approximately 180 degrees about the-pin61 to the positioirshown iii-dotted lines in Fig. 5, it constitutes means for holding the Window partly open for purposes of ventilation. The handle 62 is provided with a hook 6? having an abutment surface 68 adapted to engage the frame flange 14. It will be obvious from an` inspection of the structure shown in dotted lines in Fig. 5 that this arrangement will serve to hold the sash partly open with respect to the frame and prevent accidental opening' or closure thereof.

While the invention vhas been shown and described in great detail for the purpose of adequate disclosure, they'broadl idea of the invention is not to be limited to any of the details shown or described but includes such embodiments thereof as come within the scope of the siibj'oined claims.
